Set-up and Installation 

Preparing the Milling Machine for Service 

1.  Remove any crating which may be covering the 

machine on the pallet. 

2.  Remove accessory items from the pallet or 

machine table. Compare these items with the list 
on the previous page. 

3.  Check the tightness of the lifting ring on the ram 

to be certain it is tight. 

4.  Check the tightness of the lock handles on the 

ram (see Figure 23) to be certain the ram is 
locked tight. 

5.  Remove the nuts and/or bolts, which secure the 

machine to the pallet. 

6.  Center an overhead crane or other suitable 

overhead lifting device and sling arrangement 
over the lifting ring. 

Note:

 This machine weighs over 2400 pounds! 

Be certain the lifting arrangement is new or in 
excellent condition and has a safety factor that 
will account for age, difficulties in lifting, etc. 
When lifting using the ring, the machine will tip 
forward. If you wish, you can minimize this tipping 
by rigging a support sling over the front of the 
machine. Be careful when doing this, to prevent 
the sling from damaging any components on the 
front of the machine. Be sure to steady the mill to 
prevent it from spinning. 

7.  Lift the machine off the pallet no higher than 

necessary to clear the hold-down hardware, then 
pull the pallet out of the way. Do NOT get hands 
or feet underneath the machine when removing 
the pallet! 

8.  Put the machine base over the hold-down system 

where the machine will be spotted. Anchor bolts 
of sufficient size and length must be fastened to 
the floor according to the footprint of the mill. See 
diagram on page 10. 

Note:

 The accompanying diagrams show you the 

maximum dimensions of the machines with the 
table, ram, etc., fully extended in all possible 
directions. When spotting the machine be certain 
to leave room not only for the machine itself, but 
also for operator clearance and clearance for 
workers servicing the machine, and any unusual 
sizes of workpieces that might extend off the 
machine’s table. 

9.  When the machine is over its anchors, level the 

machine using shims under the corners needing 
them. The machinist’s level used for leveling 
should be placed on the table. The table is the 
reference surface for both side-to-side and fore-

and-aft leveling. Be certain you get it level in 
BOTH directions. 

 Mill must be supported equally 

under all four corners. Failure to comply may cause 
the column to twist and put a bind in the table ways. 

10. When the machine is level, secure the base to 

the anchor system. 

IMPORTANT:

 Before attempting to raise the mill 

head, refer to Mill Head – Left/Right Adjustment in 
the 

Adjustments 

section for procedures to safely 

raise and set up the mill head. 

11.  Loosen the four hex head nuts (see A, Figure 22) 

about 1/4 turn each (counterclockwise), just 
enough to allow rotation of the head. 

12. While assisting the worm mechanism by putting 

upward pressure on the motor by hand, use the 
wrench supplied with the machine to turn the 
worm nut and raise the head to upright position. 

13. Tighten the headbolts slightly — not torqued — 

just snug. 

14. Using mineral spirits or other cleaning solvent, 

clean all of the rust proofing from where it may 
have been applied. This is important; moving the 
table or any other components before removing 
the rust proofing will only put rust proofing where 
you don’t want it. 

Some of the following steps may have already 
been performed on the machine. If so, ignore the 
instructions related to those particular steps. 
Otherwise, perform them in the order listed, 
referring to Figure 11 for any clarification. 

15. Install the table traverse and cross-feed cranks 

on their respective shafts using the nuts on the 
shafts to secure the cranks. 

16. Remove any rust proofing from the drawbar and 

its washer, and put the drawbar with washer 
installed into the spindle center through the top of 
the machine. 

17. 

Slide the fine feed handwheel over the 
handwheel hub and push it back until its rollpin 
engages the hole in the hub and the wheel is 
flush with the hub surface. 

18.  Put the coarse feed handle on the feed shaft and 

tap it lightly until its roll pin engages a hole in the 
hub and it is flush against the hub surface. 

19.  Unwrap and clean the knee crank and install it on 

its shaft. 

20. Install the rubber way covers at front and behind 

the table.
